Branstad signed off on more than $4 million approved by lawmakers. It establishes the Statewide Interoperability Communications Network.

"When an emergency event happens, and an Iowan calls 911, they deserve to have first responders that can communicate with each other via a radio system," Branstad said. "This bill helps to make this a reality for our state."

It will allow police agencies to communicate on a single system. That makes it easier to coordinate responses to emergencies and natural disasters.

"The state is providing a clothesline across the state, if you chose to hang your clothes on it, you can, for coverage we are going to provide 90 percent signal coverage, mobile coverage with a radio with this system,” said Sgt. Tom Lampe with the Iowa State Patrol.
